The TetraMouse is a low-cost, full-featured, dual joystick computer (or AAC device) mouse designed to be operated with the lips by people with little head movement or with the tongue (special cup-shaped knobs available) for those with no head movement.

One joystick positions the mouse pointer and the other performs left, right, left click and hold, right click and hold and middle (scroll) button functions as well as selection of four adjustable pointer movement speeds and custom user programming of speeds and multiple speed configurations.

Speed control and positive positioning make this unit capable of precision mouse operation in demanding applications while still easy to use for web browsing or word processing.

No additional software is required (the computer "sees" it as a standard mouse). The TetraMouse requires no physical connection to the user, increasing the user's independence.

The latest model TetraMouse (Model TM05), is the result of four years of continuing research and development and now offers more features in a smaller package than previous models, while remaining the most affordable and practical mouse of its type with the longest warranty of any head operated mouse on the market.
